About the dish

Peking duck: crisp lacquered roast duck carved at the table and eaten in thin pancakes with scallion, cucumber and sweet bean sauce.

How the picture comes apart

From the frame to the center the picture is 12 layers deep. The outer ring is mostly dark red and grey, the middle band is mostly grey and orange, and the core is mostly brown and orange. Ants can only reach the next layer once the one around it is gone, so the core colors are the last to become useful.

By block count the biggest colors are grey, dark red and black.

The 2 golden key(s) are buried in the middle band of the picture, so the locks they open come into play around the middle of the level.

The spider web covers 24 cells in the core of the picture and needs 36 bites from soldier ants.

1 number block(s) take 18 bites in total.

14% of the blocks are frozen and take two bites each.

Reading the tray

The tray starts with 43 boxes in 4 columns. At the start 3 of the 4 front boxes can bite right away: black (bites now), black (bites now), black (bites now) and yellow (has to wait).

Chained pairs start in column 1–2, row 2, column 1–2, row 4, column 1–2, row 5, column 2–3, row 6 and column 3–4, row 5.

Locked boxes start in column 4, row 8 and column 4, row 10.

3 mystery box(es) only show their color when they reach the front.

The tray is a conveyor: every 3 taps the front row shifts one column to the right, and the rightmost box wraps around to the left.

3 soldier box(es) carry the bites for the web.

How the verified run plays out

The solution further down was played to the end in the real game, with ants walking and real timing. It takes 38 taps. The chart shows how many boxes were still parked in the 5 slots, waiting for their color, just before each tap.

Opening (taps 1–11): 38% of the blocks are eaten, with up to 2 of the 5 slots holding a box that is waiting.

Middle (taps 12–24): 29% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

Ending (taps 25–38): 33% of the blocks are eaten, with up to 2 of the 5 slots holding a box that is waiting.

A key comes out before tap 18. A key comes out before tap 28. The web breaks before tap 26. Chained pairs are taken at taps 5, 11, 15, 16 and 21.

How hard is it?

Two test players attempted this level many times: a cautious one that only sends colors it can use right away cleared it 9% of the time, and a look-ahead one that tries each option before committing cleared it 15% of the time. Most of their failed attempts jammed in the middle.

Strategy

Check the colors of the first three boxes in each column and compare them with the colors exposed on the outer ring of the picture. Always keep one slot free to catch a color that can't be eaten yet.

Tight from start to finish. Only take boxes that can send ants immediately, watch the second and third rows of the tray, and plan the next tap ahead.

Keys are buried in the picture and must be dug out to open the locks in the tray. Prioritize colors that eat around the keys so locked boxes don't block the front row for long.

Ice blocks take two bites, so one block uses two ants. Icy areas are eaten slowly and the matching boxes stay in their slots a little longer.

Nothing under the spider web can be eaten. Wait until the edge of the web is exposed before sending the soldier box (the leafy green one), or it just occupies a slot.

Number blocks take many bites; the number is how many remain. They can be bitten as soon as any side is exposed, and several boxes of that color can work on one at once.

Chained boxes need both halves in the front row and two free slots. Take the boxes in front of them first and free two neighboring slots in advance.

Mystery boxes show their color only when they reach the front. When you see one coming, don't fill every slot; leave room for it.

The conveyor moves the front row one column to the right every few taps. Before a turn, take the color you need if it is about to slide away; a box you don't want yet may be moved aside for you. Locked boxes and chained pairs stay put.

Step-by-step solution

This order of taps is verified to clear the level. Columns are numbered 1–4 from the left; after each tap, wait until the ants are out before the next one. Two boxes shown together are a chained pair taken in one tap.
